Abstract (en)
[origin: EP2641956A1] A non-asbestos frictional material composition is provided, which is capable of provide a frictional material with excellent shear strength, anti-crack properties, and abrasion resistance, even with the reduced content of copper. Furthermore, a frictional material and a friction member formed by using this non-asbestos frictional material composition are provided. The non-asbestos frictional material composition containing a binder, an organic filler, an inorganic filler, and a fiber base material includes: copper in a content of 0.5 mass % or less as a copper element; a metal other than copper and copper alloy in a content of 0.5 mass % or less; an acrylic elastomer-dispersed phenol resin as the binder in a content of 7-15 mass %; and Ca(OH) 2 and/or CaO as the inorganic filler in a content of 1-5 mass %.
